Could not build application for the simulator for flutter(无法为颤振模拟器生成应用程序)

问题描述

我已经做了所有事情，并在Pod文件中将iOS版本更改为10，但仍然收到错误。

推荐答案

此错误可能由多种原因造成。

• 首先，使用⌘ + B在Xcode中构建应用程序可以发现一些本机错误。如果是这种情况，那么您可以解决错误并尝试在Xcode本身中构建应用程序。如果它在构建过程中成功，则您的应用程序将从模拟器运行。

• 其次，尝试更改Xcode中的iOS版本(如果尚未更改)。

• 第三，它可能是由于Pod中的一些变化而发生的。要解决此问题，请执行以下步骤：

  • rm ios/Podfile

  • flutter pub get获取包。

  • 从目录的iOS文件夹中删除Pods文件夹。

  • cd ios则pod install

  • flutter clean

  • 运行项目。(如果您使用的是VSCode，请按F5)

我希望这解决了您的问题。
